researching wave makers for my 125g freshwater tank. I currently have two Hydor 850's but one that was brand new just stopped working and I am sending in for a replacement.

Opinions on the Hydor SmartWave pump ? Says you can attach two units to it.

I have seen the Jebao wavemaker as well and was not sure which direction to go in.

Also looking at an Ocean Pulse brand that others have said can run the Koralia's on and they have a model where you can hook up a total of 4 of them. However the manufacturer says not to run them with this wave maker.

So looking for some advice and/or problems others have encountered using these products. Thanks.
